Topless Mario Lopez To Rehash Day's Celebrity News For Floundering 'Extra'Mario Lopez, the dimple-cheeked actor who first rose to prominence playing the deeply conflicted Albert Clifford 'A.C.' Slater on the Chekhovian scholastics drama Saved by the Bell, has been announced as the new host of Extra. As we mentioned yesterday, ratings were declining steadily for the syndicated celebrity newsbite service; Warner Bros. was therefore looking to drop its current hosts (Mark McGrath, former lead singer of the Afro-Caribbean-flavored pop outfit Sugar Ray, and Dayna Devon, who apparently is not Nancy O'Dell) in favor of something fresher, absier, and more Eva Longoria-accessible. Weekend co-host Lopez fit that bill: "'He will be a fresh and dynamic presence, and we can't wait for him to assume his new role,' said senior exec producer Lisa Gregorish-Dempsey." Look for new features like the VitaminWater presents Extra's Live! From the DKNY Beach House!, and the Mario Lopez's Knockout Fitness Gym Couture Fashion Report.
